To all whom it may concern:

Be it known that-I, JAKoB Gnoon, of 19 .-Du.na'rd road, Rutherglen,Scotland, confec- I tioner, have'invented a new anduseful Process forthe Manufacture of'Chocolates, the same being also applicable for the"making of soluble powdered cocoa, of which the following is aspecification.

' My invention relates to a process for the manufacture of all sorts ofeating and dessert chocolates, the coating of all chocolates, thecaramelizing of milk and sugar for milk chocolate, andthe caramelizingof all kinds of nut paste for all'filling purposes, as Well as, for theroasting of the cocoa-bean for making easily soluble powdered cocoa,,and-

' has for its object to reduce the-cost of manu factureof suchchocolates, and, through this rapid roasting and cooking process, retain20 all the cocoa-butter. present the cocoabean, and all the valuablechemical constltuents required in standard spe'cialchocolates,

v brings'up'a heat from" say 270 to 350- Fahrenheit', and; at the sametime,- if deand thereby obtain a much 'finer flavored chocolate thanhitherto. According to my invention, I roast, cook and pulverize thecocoa-beans or nuts by means of friction, in place of by steam or suchlike heating medium, which friction sired, I convert the sugar-which isnot "in any way previously treated or prepared ,into caramel, the twobodies; being dealt with simultaneously in the manufacture ofchocolates,wthe process being, effected from anything between 35. and 60.minutes. Y

w re n-t o In cases where cocoa-beans of good quality containing a highpercentage of butter are to be dealt with, theheat engendered byfriction need not be allowed to rise above.

270 F. or even lower, while, where hard beans with a lower percentage ofbutter are 'in question, higher temperatures are neces-' to bring outthe full flavor which can sary v be attained by my'new process.

Any suitable machine maybe used in the I ,process to serve the jointpurpose of roast-. ing, cooling and pulverizing. the beans, mix.-

mg the powder with the sugar and raising the necessary temperature byfriction, the only essential being that sufficient churning and rubbingof the particles "may. take laee to liberate the: necessary heat. ,Forexample, asa type-of apparatus which will perform the process, a machinecanbeilsed t of r d o at g p e Specification of lietters Ilatent.

1]. A process for. the manufacturev'of chocolates consisting, insubjecting the cocoa 05 beans'to a churning and-rubbing action,liberating the heat necessary for roasting,

erating the heat necessary for roasting, cooking and pulverizing'thebeans by the friction developed during said action, caramelizing sugarbysaid heat, mixing it with the pulverized bean, and .finally roasting,

cooking and pulverizing the beans'by said lolheatlfor providing a pastefor filling purposes, substantially as described.

3. A process for the manufacture of milk chocolates consisting in theapplication of friction for caramelizing the milk and sugar,substantially as described.

. 4. A process for the manufacture of soluble powdered cocoa, consistingin the application of friction, and in the roasting, cooking and,pulverizing of the cocoa beans thereby, substantially as described. InWitness whereof I affix my signature: JAKOB GLQOR.
